So I downloaded the free version to take a look and just a FYI a couple of the pages just went to a blank screen (about and when you click the component name from the component drop down)
Might have been a bad install not sure but it was locally done on Joomla 3 if you are curious.
Now my real question is this, when will Google+ be available? I have gone through all the posts and there is mention about an API so is this something the user client (me) needs to do or is that something you are waiting on? I noticed it on the roadmap as high priority from 8 months ago and my client insists on Google+ as well so I would be happy to purchase the pro assuming Google+ has a reasonable release or workaround.
